This invention relates toa printingform.

wherein one part is relatively permanent' for many impressions and anotherpart is periodically changed, as, forinstance, in an addressing machine. One object of the 1nvention is `to combine means. for printing the body ofA a .form by rows of`individual typewith means for printing thechangeable portion by embossedA character strips held l0 parallel with the type rows and arranged to stand atthe same printing height.

. Another object is to yprovide afsimple and inezipensive device which may be mounted on the carrier for the general form and enablethejready interchange of the members printing the changeable portion. r

y A more particular embodiment of this invention is in connection with a multigraph having' a rotarydrumon which are mounted .rows oftype. lMy removable-insert is adapted for readymountingpon such railed drum and adds to the type form a few lines adapted to printing in'conjunction therewith, but readily changedl without disturbing the' type on thefdrum. H

` y More specifically my removable insert comprises av plate'having means on itsunder vside adapted to extend between the lT- rails of a multigraph machine land under- .hang the heads thereof, and having meansV for carryingk on its upper side, a removable printing member.y

The invention 'hereinafter is more fully explained inconnection with the drawings and the essential novel characteristics are ysummarized in the claims.

Invthe drawings, Fig. 1 isv an end elevation, partly broken away, of a multigraph drum, equipped with rows of lindividual type and my removable insert; Fig. 2 is a fragmentary plan of such drum so equipped:

Fig. 3 isa crosssection through the Yremov-V able insert device; Fig. 4 is a perspective of the `holder member of the removable inv4:5 sert, which is directly mounted on the drum; Fig. 5 is a perspective of the lock for'the holder. .1

In Figs. 1 and 2, A 'indicates a multigraph drumv having about its periphery prbo allel rails a with overhanging edges. B indicatesshorttype grooved on its opposite sides and adapted to be lslid endwise of the rails intothe space between them, such type being retainedin place by the overhanging serial-@Na 159,152.v

headsfofthe'raila and, if desired, prevented from laterally shifting by Astop plugs or clips, C (Fig. 2) mounted in the channels. The parts described ,constitutev usual multigraph equipment with ywhich my removable. y'insert is ldesigned to cooperate. My` removable insert', f in its preferred form, comprisesasheetmetal holder plate 'having-upwardly and inwardly vcurled parallel, edge. l,flanges and 'a platecarrying embossed .characterswhichis adapted to be sl1d;read1ly.intoand .out of placein the holder. '.The holder andfitsremovable print;

ing'member are of such combined thickness that the lprinting .characters stand at4 the same radialjdistance from' theaxis 4of the drum as'the face of the type B.

The holderforthe removable insert,r.desig y i nated. .10, ,comprises a. plate,k havin underside means. for .holding iton tie drum and y,on lits yupperside means for holding the changeable .printing device. As 'shown' in Flgs. VSiand/l, the-holderfplate 10 has on lts underside i longitudinal railsf 11Y .which are. of Linverted. T-shape in cross-section. These railsf may be weldedl ox-jotherwise sev.cured ,to the platel 10.V This `platehas its ,edgesv curled `under upwardly and inwardly to provide fthe hooked A,flanges 12. Such a holdermay be readily'mounted on the multigraph kdrum. by being slid .lengthwise theyreof, lthe Vrails 11 beingjsopositioned on the on its f.

plate..10 that 4theyjregister with channels l' between someof therails a on the drum.

prefer to employ as the .changeable printing ,member a thin sheet meta] carrier plate which has upwardly stamped projections on which aremounted flanged vstrips embossed with vthe printing characters. As shown moreparticularly in Figi 3,; this carrier plate 2O has parallel rows ofupward- Ivy-projecting buttons,2'1 stamped u from the plate and` connected with it in dlrection ofthe row, but disconnected Vat the edges, y.whichV project freely toward adjacent rows. Such fa plate .is shown, described, and claimed inthe patent to W. J. Deming,lNo. 1,438,584 issued December 12th, 1922, to The American zMultigraph Company. In addition.. tofthe stamped up buttons, the plate preferably has also upstanding corrugations 22 betweenrthe buttons, which act tovstien vthe plate 'and with the buttons provide a.'

Continuous supportfor the embossed strips.

This feature is covered in Patent No. 1,438,- 582 of B. J. Craig, issued December 12th, 1922, to The American Multigraph Combe slid endwise over the row'of buttons and be retained thereon by reason of the flanges on the strip underhanging the arcuate projecting edges of the buttons.

` Simple means may be employed to present the embossed strips shifting longitudinally on vthe lplatey 20. This may be eii'ected the lsimple expedient of makingvan inward dent by prick'punch on :some blankspace on the strip. If desired, I may form an abutment for'these strips at one end by inserting a fiat flexible strip of metal transversely `of the rows through the space beneath aligned buttons.y Such an abutment strip is shown at 23 inFig. 2 and is claimed in my co-pending application N`o.'673,413, filed November 8th, 1923. v

It lwill be seen that the embossed strips, made by some suitable machine, may be quickly mounted and secured-on the. plate 20. Likewise, such plate with the strips may be quickly mounted in the holder 10 and the holder 10 maybe quicklymounted on the multigraph drum.

If desired, the holder maybe prevented from shifting laterally on the drum bythe use of the usual plugs or clips such as shown at C for locking the. type lines. However, I regarded it preferable to providea special lock on the holder 10. I have shown, such lock in the fom of `a screw 40, the shank of which passes through a hole inthe holder, and a nut 41 threaded thereon and occupymg one of the channels of the drum and pre-y vented from rotating by engagement with the side walls vof adjacent rails of the drum. Such screw is so located in the plate 10 that the nut aligns with oneof the channels when the rails llaligns with otherv channels and such holder is slid into place on the drum, when thescrew is turned by a screw driver, the hol'der'becomes clamped to the drum. Thel head of the screw Aperforms another function, forming an vabutment for the plate 20. Accordingly, by properly positioning the holder on the drum, the plate shoved lengthwise against the screw head comes intothe proper position to have the embossed strips held by the positioning strip 23 in proper registration with the rest of the form onthe drum.

I have found it usually suicient to lock the holder in position and use the head of the screw 40 as an abutment for the plate,

the latter fitting the overhanging edges 12 of the holder with suiiicient snugness so that itdoes not become displaced in operation of the machine. able clip may be inserted in one of the channels at the other end of the holder and bear against thatend of the plate and thus positively prevent its shifting in that direction. It will be noted that the removable insert as described is adapted for mounting on a railed member whether the latter be a rotary drum or a flat bed. If the device is usedon aiiat bed the holder plate 10 is madeiat and both rails 11 have their webs vertical. Then the holder is intended for mounting on a drum the plate r10 is'preferably curved concentrically of the drum surface and the rails 11 are positioned radially thereon, as shown in Figs. 3 and 4.

` If the printing member comprises the plate "20 with removable embossedstrips 30, which is my preferred form, it will be seen that thesame plate may be used over and over again with different embossed lines thereon. In such case the ordinary equipment for this attachment may well comprise one holder 10. several plates 2() and the requisite embossed lines, these embossed llines tobe made up according to the diii'erent matter to be inserted and mounted on different plates 2() when the body of the form is von the drum and the hold-er locked in place in proper position with relation thereto,vone plate 20 with its embossed strips may be slid into place 1n the holder and the desired number of However, if desired, a Suit-- copies run off, the machine stopped, and the plate 20 with its strips slid out and another plate withstrips substituted." The plates 'and strips occupy a small space and may be stored in -assembled condition' for subsequent use, or the embossed strips may be removed and others mounted on the plate, according ton the nature of the printing operation. f

It will be seen that my invention provides a simple device for enabling vcomposite forms to be made, comprising type and embossed l material all standing at the same printing height. This is true whether the changeable printing member comprisesa stamped plate with kseparate embossed strips thereon or is otherwise constructed.
